AC controller fault

What happened?

The printer is showing the message "Fan 1 of the heated bed is operating outside of specification".

Error name: AC controller fault

Error code: #35336

How to fix it?

Locate the fan on the bottom of the heatbed. If needed, raise the heatbed by navigating to the LCD Menu -> Control -> Autohome. Once the printer is moved to the needed position, do not manipulate it until it is fully cooled down and switched off. 

Check the fan for any dust or debris, and clean the residue if needed. 

If this does not solve the issue, do not hesitate to contact our technical support, as a component hardware replacement is most likely needed.
